원문이 있어야 정확한건 알수 있을것 같은데요
클로즈 테그를 잘 캐치를 못하네요. .+에 <를 제외 시켜 주세요.

top_company 와 condition_tit 이 
한꾸러미에 들어있지 않아서 정규식만으로는 힘들겠네요!
html 라이브러리를 사용하시던지 만드셔야 편해지겠습니다.
정규식을 제대로 사용하려면 구간의 시작과 끝이 
확실해야 하더군요!

한글이 깨지는 경우 이렇게 호출하면 나오네요!
   $text = curl_exec_utf8($ch);
   //$text = curl_exec($ch);
아니면 이렇게
  foreach ($matches[1] as $match) {
    echo iconv('EUC-KR', 'UTF-8', $match) . '<br>';  
    //echo $match . '<br>';  
  }
